Now, comes the part where we are supposed to be doing the software configuration to properly set our pfSense and make it work properly. To better understand have a look at the image below. Now the thing to remember here is that pfSense needs two network adapters to function, now the question is why? pfSense needs these two different network adapters because it acts as a gateway between your LAN and WAN. After downloading the file I made a blank Virtualbox environment for a 64-bit FreeBSD machine and then loaded on the. Now, after going through few videos regarding pfSense on YouTube I went ahead and downloaded the pfsense.iso file from their website. I already had VirtualBox downloaded and installed on my system. The next plan was to look around the functionality pfSense provides by default once the setup was done properly. So, now that it was decided that I will be working on pfSense, now comes the part to set it up on my virtual box environment and see if it works properly. ’Cause anyone who has used firewalls know that the rulesets and the tools used must be configured meticulously, if not then either it will generate too many false positives or it will just let next to all traffic pass and none of those conditions are actually useful to us. The best solutions that I came up with involved pfSense, so I thought why not set it up at my home and then experiment on it before deploying it in a live environment. Once this project got completed then I began working on other projects and configuring the firewall was the next thing I wanted to try out.

The previous week I was working on a combination of OSquery and ELK stack for enhancing the logging capabilities. I have just joined a new organisation where for the first time I have been seriously working on the blue team and setting up security measures while figuring out ways to find a loophole and then fixing it along the way. Well, enough of my ranting for today now let’s talk tech! Backstory I don’t guess I could have asked for a better job as my first job. Working in a company that helps you grow and lets you freely tinker around with the technology you want to learn and implement is the best work environment one can ask for. Integration of Pfsense with Suricata, Snort & Squid to enhance network security!
